Glock 20 900fbs?

[Bazzer]

I read a post recently where someone claimed to exceed 900fbs from a standard Glock 20 in 10mm.  This is equal to the .460 conversion.  Is this possible with a severe risk of blowing up the gun?

I am no expert by any means.

But we have ammo in the 800 foot pounds of energy listed on the sheet. The newer Glocks (2011+) have been firing the hot ammo without a hitch.

I would venture a semi educated guess that with a light bullet and high KE we could get into the 900 foot pound area.

Welcome to the forum, BTW.

Thanks, I am new to the forum, but not new to shooting.  I'm very pleased with my 10mm Glock and I'm just starting out on the learning curve!

The Glock 20 is an excellent platform!

Here is the sheet I was telling you about. It looks like the Doubletap 135 grain gets up to 891 ft/lbs out of Intercooler's 4.75 inch Witness.

I am betting some of the lighter bullets, when loaded to full potential, will easily get into the 99 ft/lb range.

Here is a round that makes it, yes it has been done...

10mm using 135 Grain @ 1735 fps is 902 ft lbs energy

Kevin's NFP 155gr is basically there:

UNDERWOOD    NOT FOR PUBLIC!!   155      SPEER   TMJ   1,600   1599   1,660   880   949   IMR 800-X   11.2            

I'm sure you could push it a little more into the 900lb range with a smidge more powder. You have to have a well set up firearm to push those numbers though!!!
